SPATIAL STRUCTURAL ANALYSIS AND TEST STUDY OF A THREE-SPAN PRESTRESSED CONCRETE SUPER-WIDE CITY BRIDGE

摘要：

Super-wide city bridges emerged with the development of social economy, city scale and vehicle volume. Since the span-to-width ratio is small, the super-wide bridge should be analyzed based on the spatial structural analysis theory not the plane member theory. In this paper, study status of super-wide city bridge is briefly introduced. By using the ANSYS program, the spatial finite-element (FE) analysis of a three-span prestressed reinforced concrete super-wide city bridge of continuous box girder is presented. Combining field static loading and ambient vibration testing, the structural static and dynamic characteristics of super-wide city bridge and future applications are explored.
